Abstract
A vehicle security system includes a vehicle security sensor and associated sensor bus interface, an alarm indicator and associated alarm indicator bus interface, and an alarm controller and associated alarm controller bus interface for interfacing the alarm controller. The vehicle security system is for a vehicle of a type including a data communications bus connecting a plurality of vehicle devices. The security system preferably further includes a desired signal enabling circuit for enabling the alarm controller to operate using a set of desired signals for a desired vehicle from among a plurality of possible sets of signals for different vehicles. Accordingly, the desired signal enabling circuit permits the alarm controller to communicate with the vehicle security sensor and the alarm indicator via the data communications bus so that the alarm controller is capable of operating the alarm indicator responsive to the vehicle security sensor. The desired signal enabling circuit may preferably include a memory for storing a plurality of respective sets of signals for different vehicles, and a selecting circuit for selecting the desired set of signals from the plurality of different…
